My invention relates to apparatus for dis- I pensing liquids such asroot beer, birch beer,

cream ale, etc. which, either because of the tendency. to foaming due to'the high pressure.

under which they must be vended or because of the condition of highfermentation as with ale, cannot be drawn and served directly from the'package, tank `or receptacle in which they are stored. lf the liquid bedrawn directly from the tank, it is necessary to -wait a long time forthe foam to settle so as to secure a sufficient body to form a salabledrink, while on the other hand, if the liquid be drawn o5 into asecondary receptacle and left there for a long time so as to settle intoa completely -solid condition, it will,

if not soon used, become stale.

The object of my invention is to provide an apparatus of cheap andsimple constructionand capable of'rnore ready adjustment and uniformaction `than previous forms of vapparatus designed to dispense liquidfrom a source of charged liquid supply in y two streams by the use of asuitable double draft dispensing faucet, still liquid reservoir andconnections direct from the faucet to the charged liquid supply and fromthe still. liquid reservoir on the one hand to the faucet and on theother hand to the charged liquid supply.

To this end my invention consists in the special combinations ofapparatus herein after more particularly described and then specified inthe claims. y p

In the accompanying drawings, Figure l is a general vertical section andside elevation `of an apparatus' embodying my invention,

the dispensing faucet being shown in side elevation. form of floatcontrolled valve that may be used for the settling or expansion chamber.

Fig. 3 is a vertical section through a form of7 dispensing faucet whichl prefer to employ. Fig. 4 is a general plan of the same showing therelation of the various ports to the disk therein and to the pipes,leading through the shank' of the faucet and adapted. for connec- Fig. 2is a vertical section of a tion with pipes leading from the settling orexpansion chamber and the tank or package containing the charged liquid.Fig. 5 is a horizontal section taken on Athe line 1 1, Fig., 1.

In the preferred form of carrying out my invention, A indicates theouter casingof the apparatus which may be of wood or any other suitablematerial and in the form of a barrel orfin any other suitable form.

B indicates an inner casing supported on the bottom of the outer casingA. and separated. from the main body portion of the outer casing by aclosed air space surrounding the innervcasing B.

C indicates the reservoir containing the liquid in a still conditionsupported within the upper portion of the inner casing B and separatedfrom the inner casing by a space in which the ice for cooling is stored.

P indicates a double draft dispensing faucet of any suitable characterhaving connections direct to a storage tank or receptacle G containingthe charged liquid and to the still li uid reservoir C, the latter beingon the ot er hand connected also to the charged liquid. su ply G throughan automatic valve controfled by a float and adaptedto replenish thecontents of the still liquid reservoir, as will be hereinafter moreparticularly described. The dispensing faucet F is of suitable characterfor dispensing liquid directly 'into a "drinking glass or mug and may bemade as hereinafter more forth.

H indicates 'a pressure reducing and regulating valve interposedbetween` the charged liquid supply G and a conduit which passes upthrough the bottom of the casingA as shown, the conduit being elongatedand coiled to form suitable coils E and connects with a 'lV-joint orcoupling markedF. From the `latter a branch pipe or connection j' iscarried through vthe walls of ythe inner and particularly set outercasings to the faucet and another branch i or connection to an inletvalve I which controls the fiow 'of the liquid from the charged liquidsu ly G into the still liquid reservoir C.

The coils E are preferably supported in the space below the still liquidreservoir C, which constitutes-a cooling chamber, by means of a platformsecured to the inner casing B somewhat above the bottom ofv the loutercasing and forming a supplementary bottom for the .casing B. Thisrefrigerating chamber 'is 1n communication withthe ice storage spacetim) between the inner casing B and reservoir C so that the icedwater-from the ice storage space will flow into this chamber andsurround the conduit D entering the chamber, the coils E and itsbranches located therein and also envelop the lower part of thereservoir C. As iced water is a better cooling agent than ice itself,all the liquid would remain in a cold state by the use of a comparatively small amount of ice. A suitable over-k flow drain pipe might beused as indicated at Q so that the iced water vwould notl run olf untilit had reached a desired level above the liquid in the reservoir C.

M indicates the mouth of the valve l through which the liquid fiows intothe still liquid reservoir C, its flow being controlled aun tomaticallyby the action of a float li. rlhe float L is attached to the arm K by arod which may be secured in any position on 'said arm by means of a'setscrew L to thereby vary the height to which the liquid may rise in thereservoir before the valve shall shut ofi' the flow from'the chargedliquid supply G. As shown, the dispensing faucet is located just belowthe level of the outlet from the reservoir and so that the liquiddischarging i from said reservoir under slight liquid head will not becaused to foam excessively in the Aact of passing through thevalve-passages and outlet.

O indicates the pipe forming a still liquid .outlet from the reservoir Cpassing referably through the cooling chamber and t rough the walls ofthe inner and outer casings and across the space between them to thedispensing faucet located outside the casing A. The outlet O makesconnection with the liquid in the reservoir C preferably through thebottom thereof and is of such size as to allow the liquid to flow withcomparative freedom. By this construction all the liquid may bedrawnfrom the reservoir C and without ex cessive foaming.

The preferred construction of the valve l is more clearly shown in FirJr2. A stem j of 'the valve worksfin the outlet pipe M and is yprovidedwith a laterally extending pin or pins m for engagement by a hook orextension forming the short arm of pivoted lever K, so that when thefloat L falls, the stem of the valve will be lifted and liquid permittedto flow from an expansion chamber insaidl valve through the outlets ofthe valve and into the still liquid reservoir C; The conneqtionof pipefwith'the valve body is made N is a suitable adjusting or throttle valveinterposed in the connection from f2 to the valve that controls theescape of `liquid through the outlet into reservoir C. By means of thisvalve the size of the passage 'through which the liquid is supplied tothe reservoir may be regulatedvto adjust .or

f vary the flow into the reservoir according in the disk.

sans is to the demand made upon the temporarily accumulated quantity ofstill liquid by operation of the dispensing. faucet. When the liquid isdrawn off more frequently from the reservoir, said valve is openedslightly so that a larger lstream may besupplied to the tank, but aswill be obvious the pressure under which said larger stream flows willbe the same as with a smaller stream, and

hence there will be no increased tendency to foam in the dischargedstream discharging into the reservoir and no excessive foaming thereinbeyond the capacity. of .said reservoir operating as a settling tank. Ifon the other hand, the demand at the faucet is small, the valve N may beadjusted to curtail the flow. By adjustment of the float the averageamount of liquid stored temporarily in the reservoir may be regulated,so that the height of 4liquid' therein. shall normally stand at a'higher or lower level according to the maximum probablev demand ma'de onthe contents of the reservoir by the operator. As will be seen, nopractical variation of the head under which the liquid is drawn -fromthe reservoir will be introduced by these adjustments and under ordinaryconditions the liquid will flow out of the reservoir without beingsubjected to any pressure of gas from the original supply source,whereas in some previous constructions of apparatus employed for asimilar purpose not only is it necessary to employ pressure upon thesurface of the liquid in the tank used as a settling tank in order toforce it to the. higher level at which thev faucet is situated, but theconstruction necessitates also a pressure which varies with the demandand likewise varies as the level of the li uid falls nearer to theoutlet from said ta r through which the liquid passes to the dispensingfaucet..

The dispensing faucet in its preferred form comprises a disk W turningon a seat X and' provided `with a suitable operating handle connected.to the stem on which the disk is secured. The seat X is preferably madeor provided with some compressible substance in which annularsealingrings on the face of the disk W will impressi-filiera selves,said annular projecting rings'including between their two circumferencesan annular space in which includes the several ports disposed in thecircumference of a circle in the seat X. The disk W hasin its face portsc', ai connected by a channel b in the face thereof opposite the valveseat X and are of the same or somewhat larger size than the lower lpairof portsv C which pass through the valve seat A and witl which the portsai', may be' brought into simultaneous-registry by turning the valve toproper position; One port c opens into the lower chamber Y in the spoutof the The ports or openings care essere under pressure is drawn fromthe package' or tank G.

By placing the channel t in connection with the ports c', c of the valveseat X, a i full free stream is secured from the reservoir y C throughthe outlet pipe @passing along the shank ol the faucet P By placing thechannel l) in connection with the ports e', c, a Vtinestrean'i oi highpressure is secured from the main supply through the branch pipe j"passing along the shank of the t'aucet l). By placing the diskchannel bwith the ports c, a at the position shown in Fig. l the valve is closed.By locating the ports c', c and e, e at the proper distance apart, nostop is required for governing the disk W for at no time can the channelb form a connection between the channel supply pipes and this absence ofa stop greatly lengthens the Wear oi" the faucet. This faucet P issupplied with the usual adjusting sleeve and lock. nut permitting acontinual tightening ci' the valve should it leak.

The s out ol' the faucet is an open cham-I ber Y, t e delivery port cfor the liquid under lovsT pressure opening directlyinto it tofacilitate a free liovv, While the delivery'portl c has a very smallpipe Z attached, this pipe Z extending to the bottom oi1 the spoutcham-y ber Y, thus instr-ing a steady stream under high pressure to hedirected into the receptacle, a glass or mug.

rl`he operation of the apparatus follows: At rest, With the apparatusempty, the ports af", a of the disk W, of the faucet are at a pointWhere the vfaucet will be closed, While vthe reservoir C being empty,the float L is pendent in the tank C. rlhe adjusting valve N having`previously been tested and set at a point that will prevent the overflowof the reservoir C by reason of an excess of foam, the apparatus isnoviT connected to a tankof root beer for instance, under lhs. iressure, andthe 'lloW turned on. The liquid `will pass through theconduit to the supply Fixture F where it divides one stream passing tothe faucet l? at c, the other to the valve l whichlis open and into thereservoir from gentle, though copious, discharge although the initialpressure is 120 lbs. W hen a suilin cient quantity has entered thereservoir C -and has settled, the iioat L rises and closes the valve l.The initial test of the apparatus determines the proper point at whichto set the valve hl so as to permit the liquid faam to settle into solidand operate the loat l; to lclose the valve l ifvitho'ff l excess oifoam .lioiv c voir (l and thereby turning the disl` J nects the se largediante. from the reserY to the faucet, 'thi g L channel t', into thespout (arcani thence into the serving glass. the glass ha ig heen lille(f a" are placed in connectie. i gne ports e, c', and these latter beinget very small diameter, a vline stream under high pressure will i'lovvalong the pipes to thefaucet P througl'i the ports c, c and continuingthrough the outlet pipe Z, will deliver a highly charged and foamyliquid directly into the liquid already in the glass, imparting to theWhole drink a sparkling condition. The ccntents of the reservoir C beinglowered, the dropping of the float L opens the valve l, replenishing thecontents, and ifbut one drink be drawn, this' inflow is very slight, asthe ull filoat L is very sensitive and acts imniediso that it isphysically impossible to draw and serve drinks so often but there willalways he solid liquid in the reservoir. li, for

any reason, it may become desirable to dispense 'the contents so as toempty the reservoir C, the throttle valve N may he set so as to lclosethe valve l permanently, preventing a further inliow to the reservoir C,even though the float L drops, While still affording a'supply to thefine stream under high pres'- sure through the branch f. rlhis mightcccur near the close of a day-s business. 0n a cool day, or under anycircumstances where a smaller supply is desirable in thereservoir C, thelloat L may he lowered to any point by adjusting the set nut on thesupporting rod, this arrangement permitting the adapting of theapparatus to a large or small volume of vending.
